KNX shading & curtain controller OEM

Shutter actuators, 24 V DC motor controllers and blind modules that hold their position, report their state, and do not buzz in a quiet bedroom.

Discuss your spec How the program works

Drive & position logic

Relay or MOSFET output, current sensing, travel-time calibration, electronic position memory and slat angle control.

Motor compatibility testing

We test against the motors your market actually uses — Somfy, Becker, elero, generic tubular and 230 V AC — not just the datasheet.

Enclosure & thermal design

DIN-rail modules, in-wall boxes or motor-head housings, with thermal margin verified at full load and in stacked installations.

Batch QC protocol

100% load test, travel-cycle test and firmware version check on every unit before shipment, with the test log handed over.

Program detail

How this product is actually built

Shading is where cheap hardware gets caught. A relay that switches the motor is easy; position tracking, slat angle, travel-time calibration, obstruction detection and quiet operation in a 24 V DC system are not.

We specify the drive stage and the position logic first, then build the enclosure and the ETS parameters around it — because a shading product that loses its reference position after a power cut is a support ticket, not a product.

Channels	2 / 4 / 8 channel shutter or blind outputs; mixed configurations possible
Output types	230 V AC relay, 24 V DC MOSFET, 0–10 V control for dimming and shading combos
Position feedback	Electronic position memory, slat angle adjustment, manual override, bus-failure behaviour
Mounting	DIN rail (4–8 modules), in-wall 60 mm box, or integrated motor head
Certification	CE, UKCA, RoHS; KNX certification optional via accredited lab
Typical MOQ / lead time	From 200 pcs per variant; 10–14 weeks after design freeze

Questions

What brands ask before starting

Can you match an existing actuator footprint?

Yes — if you are replacing a product from a supplier you want to leave, we can match the DIN-rail width, terminal layout and ETS parameter names so your integrators do not have to relearn anything.

Do you support 24 V DC motors as well as 230 V AC?

Both. 24 V DC needs a different drive stage and current sensing; we test with the specific motor families used in your market before freezing the design.

What about power-failure recovery?

Position memory is written to non-volatile storage on every completed movement, so the actuator knows where the blind is after a bus or mains failure — with an optional reference run if you prefer hardware end-stops.

Is KNX certification required for actuators?

For most residential projects, a certified BCU with well-tested application software is enough. If you sell to specification-driven projects or tender documents, full product certification is worth the cost — I will price both routes.
